Thermomix Chocolate Peanut Butter Slice

Homemade Rice Bubble Bars are a regular treat in our house but if we’re looking to mix things up a little, then I will make this Thermomix Chocolate Peanut Butter Slice instead.  This is such a simple recipe and my kids absolutely love it. If you want to make it a little healthier, simply omit the chocolate layer but it’s really worth making it once (or twice!) with chocolate!

You can also use golden syrup or honey instead of the rice malt syrup if you prefer, and we’ve also tried this recipe with crunchy peanut butter which added something a little extra to it.
